A couple of days ago I upgraded to v4.0.0 and started to use "update metadata from existing musicbrainz id" to add the new tags.
During this I noticed that the artist tag for multiple recognized artists contain extra spaces. For example "Babyface<space>&<space>Stevie Wonder" becomes "Babyface<space><space>&<space><space>Stevie Wonder".
These double spaces are not automatically colorcoded but are used in subsequent "correct filenames from metadata" calls etc
Is this a bug or a changed setting somewhere?
